Owner=user-id

    Specifies the owner of the tape volume set. The owner is the
    user who will be permitted to restore the database. The user-id
    parameter must be one of the following types of identifier:

    o  A user identification code (UIC) in [group-name,member-name]
       alphanumeric format

    o  A user identification code (UIC) in [group-number,member-
       number] numeric format

    o  A general identifier, such as SECRETARIES

    o  A system-defined identifier, such as DIALUP

    The Owner qualifier cannot be used with a backup operation to
    disk. When used with tapes, the Owner qualifier applies to all
    continuation volumes. The Owner qualifier applies to the first
    volume only if the Rewind qualifier is also specified.

    If the Rewind qualifier is not specified, the backup operation
    appends the file to a previously labeled tape, so the first
    volume can have a protection different from the continuation
    volumes.

    See the Oracle Rdb Guide to Database Maintenance for information
    on tape label processing.
